North Dakota regulators may raise Otter Tail wind charge

California Wildfire Smoke Impact on Solar reduces photovoltaic output, as particulate pollution, soot, and haze dim sunlight and foul panels, cutting utility-scale generation and grid reliability across CAISO during peak demand and heatwaves.

Key Points

How smoke and soot cut solar irradiance and foul panels, slashing PV generation and straining CAISO grid operations.

✅ Smoke blocks sunlight; soot deposition reduces panel efficiency.

✅ CAISO reported ~30% drop versus July during peak smoke.

✅ Longer fire seasons threaten solar reliability and capacity planning.

Smoke from California’s unprecedented wildfires was so bad that it cut a significant chunk of solar power production in the state, even as U.S. solar generation rose in 2022 nationwide. Solar power generation dropped off by nearly a third in early September as wildfires darkened the skies with smoke, according to the US Energy Information Administration.

Those fires create thick smoke, laden with particles that block sunlight both when they’re in the air and when they settle onto solar panels. In the first two weeks of September, soot and smoke caused solar-powered electricity generation to fall 30 percent compared to the July average, according to the California Independent System Operator (CAISO), which oversees nearly all utility-scale solar energy in California, where wind and solar curtailments have been rising amid grid constraints. It was a 13.4 percent decrease from the same period last year, even though solar capacity in the state has grown about 5 percent since September 2019.

California depends on solar installations for nearly 20 percent of its electricity generation, and has more solar capacity than the next five US states trailing it combined as it works to manage its solar boom sustainably. It will need even more renewable power to meet its goal of 100 percent clean electricity generation by 2045, building on a recent near-100% renewable milestone that underscored the transition. The state’s emphasis on solar power is part of its long-term efforts to avoid more devastating effects of climate change. But in the short term, California’s renewables are already grappling with rising temperatures.

Two records were smashed early this September that contributed to the loss of solar power. California surpassed 2 million acres burned in a single fire season for the first time (1.7 million more acres have burned since then). And on September 15th, small particle pollution reached the highest levels recorded since 2000, according to the California Air Resources Board. Winds that stoked the flames also drove pollution from the largest fires in Northern California to Southern California, where there are more solar farms.

Smaller residential and commercial solar systems were affected, too, and solar panels during grid blackouts typically shut off for safety, although smoke was the primary issue here. “A lot of my systems were producing zero power,” Steve Pariani, founder of the solar installation company Solar Pro Energy Systems, told the San Mateo Daily Journal in September.

As the planet heats up, California’s fire seasons have grown longer, and blazes are tearing through more land than ever before, while grid operators are also seeing rising curtailments as they integrate more renewables. For both utilities and smaller solar efforts, wildfire smoke will continue to darken solar energy’s otherwise bright future, even as it becomes the No. 3 renewable source in the U.S. by generation.

Newfoundland and Labrador electricity rate hike examines a proposed 18.6% increase under the PUB's Rate Stabilization Plan, driven by oil prices at Holyrood, with Consumer Advocate concerns over rate shock and use of RSP balances.

Key Points

A proposed 18.6% July 2017 increase under the RSP, driven by oil prices, now under PUB review for potential mitigation.

✅ PUB flags potential rate shock from proposed adjustment

✅ RSP balances cited to offset increases without depleting fund

✅ Oil-fired Holyrood volatility drives fuel cost uncertainty

How much of a rate hike is reasonable for users of electricity in Newfoundland and Labrador?

That's a question before the Public Utilities Board (PUB) as it examines an application by Newfoundland and Labrador Hydro, which could see consumers pay up to 18.6 per cent more as of July 1, reflecting regional pressures seen in Nova Scotia, where regulators approved a 14% rate hike earlier this year.

"The estimated rate increase for July 2017 is such a significant increase that it may be argued that it would cause rate shock," said the PUB, asking the company to revise its application.

NL Hydro said the price adjustment is part of what happens every year through the Rate Stabilization Plan (RSP), which is used to offset the ups and downs of oil prices.

"The cost of fuel is volatile and as long as we rely on oil-fired generation at Holyrood, customers will continue to be impacted by this electricity price uncertainty," said the company in a statement to CBC News.

It noted that customers received a break from RSP adjustments in 2015 and 2016, even as costs from the Muskrat Falls project begin to be reflected.

The PUB noted that under the rate stabilization plan, prices have gone up or down by about 10 per cent in the past.

The regulatory board said the impact of the latest request would be a 27.6 per cent hike to Newfoundland Power, with "an estimated average end customer impact of 18.6 per cent."

Hydro's estimates are based on an average price for oil of $81.40 per barrel from July 2017 to June 2018, according to the PUB.

'Unacceptable' burden: Consumer Advocate

"To burden ratepayers with an 18 per cent rate increase is unacceptable," said Consumer Advocate Dennis Browne, echoing pushback in Nova Scotia, where the premier urged regulators to reject a 14% hike at the time.

Browne is arguing that there is money in the RSP to reduce the proposed increase, including the possibility of a lump-sum bill credit for customers.

"These ratepayer balances — which, according to NL Power, totals $77.4 million — are not the property of Hydro," he wrote in a letter to the PUB.

"No utility has the right to squirrel away ratepayers' money to be used by that utility for some future purpose. The Board has jurisdiction over those balances," Browne said.

Browne also wants the RSP overhauled so that it can be applied to price fluctuations every quarter, as opposed to annually.

Hydro has expressed concern that depleting the rate stabilization fund would lead to other, more significant, rate increases in the future.

It said several alternatives to mitigate high rates have been provided to the PUB, which has final say, similar to how Manitoba Hydro scaled back a planned increase in the next year.

Electric Vehicle Adoption Barriers include range anxiety, charging infrastructure, and cost parity; consumer demand, tax credits, lithium-ion batteries, and performance benefits are accelerating EV uptake, pushing SUVs and self-driving tech toward mainstream mobility.

Key Points

They are the key hurdles to mainstream EV uptake: range anxiety, sparse charging networks, and high upfront costs.

✅ Range targets of 300+ miles reduce anxiety and match ICE convenience

✅ Expanded home, work, and public charging speeds adoption

✅ Falling battery costs and incentives drive price parity

The automotive industry is hurtling toward a future that will change transportation the same way electricity changed how we light the world. Electric and self-driving vehicles will alter the automotive landscape forever — it's only a question of how soon, and whether the age of electric cars arrives ahead of schedule.

Like any revolution, this one will be created by market demand.
Beyond the environmental benefit, electric vehicle owners enjoy the performance, quiet operation, robust acceleration, style and interior space. And EV owners like not having to buy gasoline. We believe the majority of these customers will stay loyal to electric cars, and U.S. EV sales are soaring into 2024 as this loyalty grows.

But what about non-EV owners? Will they want to buy electric, and is it time to buy an electric car for them yet? About 25 years ago, when we first considered getting into the electric vehicle business with a small car that had about 70 miles of range, the answer was no. But today, the results are far more encouraging.

We recently held consumer clinics in Los Angeles and Chicago and presented people with six SUV choices: three gasoline and three electric. When we asked for their first choice to purchase, 40% of the Chicago respondents chose an electric SUV, and 45% in LA did the same. This is despite a several thousand-dollar premium on the price of the electric models, and despite that EV sales still lag gas cars nationally today, consumer interest was strong (but also before crucial government tax credits that we believe will continue to drive people toward electric vehicles and help fuel market demand).

They had concerns, to be sure. Most people said they want vehicles that can match gasoline-powered vehicles in range, ease of ownership and cost. The sooner we can break down these three critical barriers, the sooner electric cars will become mainstream.

Range
Range is the single biggest barrier to EV acceptance. Just as demand for gas mileage doesn't go down when there are more gas stations, demand for better range won't ease even as charging infrastructure improves. People will still want to drive as long as possible between charges.

Most consumers surveyed during our clinics said they want at least 300 miles of range. And if you look at the market today, which is driven by early adapters, electric cars have hit an inflection point in demand, and the numbers bear that out. The vast majority of electric vehicles sold — almost 90% — are six models with the highest range of 238 miles or more — three Tesla models, the Chevrolet Bolt EV, the Hyundai Kona and the Kia Niro, according to IHS Markit data.

Lithium-ion batteries, which power virtually all electric cars on the road today, are rapidly improving, increasing range with each generation. At GM, we recently announced that our 2020 Chevrolet Bolt EV will have a range of 259 miles, a 21-mile improvement over the previous model. Range will continue to improve across the industry, and range anxiety will dissipate.

Charging infrastructure
Our research also shows that, among those who have considered buying an electric vehicle, but haven't, the lack of charging stations is the number one reason why.

For EVs to gain widespread acceptance, manufacturers, charging companies, industry groups and governments at all levels must work together to make public charging available in as many locations as possible. For example, we are seeing increased partnership activity between manufacturers and charging station companies, as well as construction companies that build large infrastructure projects, as the American EV boom approaches, with the goal of adding thousands of additional public charging stations in the United States.

Private charging stations are just as important. Nearly 80% of electric vehicle owners charge their vehicles at home, and almost 15% at work, with the rest at public stations, our research shows. Therefore, continuing to make charging easy and seamless is vital. To that end, more partnerships with companies that will install the chargers in consumers' homes conveniently and affordably will be a boon for both buyers and sellers.

Cost
Another benefit to EV ownership is a lower cost of operation. Most EV owners report that their average cost of operation is about one-third of what a gasoline-powered car owner pays. But the purchase price is typically significantly higher, and that's where we should see change as each generation of battery technology improves efficiency and reduces cost.

Looking forward, we think electric vehicle propulsion systems will achieve cost parity with internal combustion engines within a decade or sooner, and will only get better after that, driving sticker prices down and widening the appeal to the average consumer. That will be driven by a number of factors, including improvements with each generation of batteries and vehicles, as well as expected increased regulatory costs on gasoline and diesel engines.

Removing these barriers will lead to what I consider the ultimate key to widespread EV adoption — the emergence of the EV as a consumer's primary vehicle — not a single-purpose or secondary vehicle. That will happen when we as an industry are able to offer the utility, cost parity and convenience of today's internal combustion-based cars and trucks.

To get the electric vehicle to first-string status, manufacturers simply must make it as good or better than the cars, trucks and crossovers most people are used to driving today. And we must deliver on our promise of making affordable, appealing EVs in the widest range of sizes and body styles possible. When we do that, electric vehicle adoption and acceptance will be widespread, and it can happen sooner than most people think.

Hornsea One Offshore Wind Farm delivers first power to the UK grid, scaling renewable energy with 1.2GW capacity, giant offshore turbines, and Yorkshire coast infrastructure to replace delayed nuclear and cut fossil fuel emissions.

Key Points

Hornsea One Offshore Wind Farm is a 1.2GW UK project delivering offshore renewable power to about 1 million homes.

✅ 174 turbines over 407 km2; Siemens Gamesa supply chain in the UK

✅ 1.2GW capacity can power ~1m homes; phases scale with 10MW+ turbines

✅ Supports UK grid, replaces delayed nuclear, cuts fossil generation

An offshore windfarm on the Yorkshire coast that will dwarf the world’s largest when completed is to supply its first power to the UK electricity grid this week, mirroring advances in tidal electricity projects delivering to the grid as well.

The Danish developer Ørsted, which has installed the first of 174 turbines at Hornsea One, said it was ready to step up its plans and fill the gap left by failed nuclear power schemes.

The size of the project takes the burgeoning offshore wind power sector to a new scale, on a par with conventional fossil fuel-fired power stations.

Hornsea One will cover 407 square kilometres, five times the size of the nearby city of Hull. At 1.2GW of capacity it will power 1m homes, making it about twice as powerful as today’s biggest offshore windfarm once it is completed in the second half of this year.

“The ability to generate clean electricity offshore at this scale is a globally significant milestone at a time when urgent action needs to be taken to tackle climate change,” said Matthew Wright, UK managing director of Ørsted, the world’s biggest offshore windfarm builder.

The power station is only the first of four planned in the area, with a green light and subsidies already awarded to a second stage due for completion in the early 2020s, and interest from Japanese utilities underscoring growing investor appetite.

The first two phases will use 7MW turbines, which are taller than London’s Gherkin building.

But the latter stages of the Hornsea development could use even more powerful, 10MW-plus turbines. Bigger turbines will capture more of the energy from the wind and should lower costs by reducing the number of foundations and amount of cabling firms need to put into the water, with developers noting that offshore wind can compete with gas in the U.S. as costs fall.

Henrik Poulsen, Ørsted’s chief executive, said he was in close dialogue with major manufacturers to use the new generation of turbines, some of which are expected to approach the height of the Shard in London, the tallest building in the EU.

The UK has a great wind resource and shallow enough seabed to exploit it, and could even “power most of Europe if it [the UK] went to the extreme with offshore”, he said.

Offshore windfarms could help ministers fill the low carbon power gap created by Hitachi and Toshiba scrapping nuclear plants, the executive suggested. “If nuclear should play less of a role than expected, I believe offshore wind can step up,” he said.

New nuclear projects in Europe had been “dramatically delayed and over budget”, he added, in comparison to “the strong track record for delivering offshore [wind]”.

The UK and Germany installed 85% of new offshore wind power capacity in the EU last year, according to industry data, with wind leading power across several markets. The average power rating of the turbines is getting bigger too, up 15% in 2018.

The turbines for Hornsea One are built and shipped from Siemens Gamesa’s factory in Hull, part of a web of UK-based suppliers that has sprung up around the growing sector, such as Prysmian UK's land cables supporting grid connections.

Around half of the project’s transition pieces, the yellow part of the structure that connects the foundation to the tower, are made in Teeside. Many of the towers themselves are made by a firm in Campbeltown in the Scottish highlands. Altogether, about half of the components for the project are made in the UK.

Ørsted is not yet ready to bid for a share of a £60m pot of further offshore windfarm subsidies, to be auctioned by the government this summer, but expects the price to reach even more competitive levels than those seen in 2017.

Like other international energy companies, Ørsted has put in place contingency planning in event of a no-deal Brexit – but the hope is that will not come to pass. “We want a Brexit deal that will facilitate an orderly transition out of the union,” said Poulsen.

Manitoba Hydro capacity constraints challenge clean energy growth as industrial demand, hydrogen projects, EV batteries, and electrification strain the grid; limited surplus, renewables, storage, and transmission bottlenecks hinder new high-load connections.

Key Points

Limited surplus power blocks new energy-intensive loads until added generation and transmission expand Manitoba's grid.

✅ No firm commitments for new energy-intensive industrial customers

✅ Single large load could consume remaining surplus capacity

✅ New renewables need transmission; gas, nuclear face trade-offs

Manitoba Hydro lacks the capacity to provide electricity to any new "energy intensive" industrial customers, the Crown corporation warns in a confidential briefing note that undercuts the idea this province can lure large businesses with an ample supply of clean, green energy, as the need for new power generation looms for the utility.

On July 28, provincial economic development officials unveiled an "energy roadmap" that said Manitoba Hydro must double or triple its generating capacity, as electrical demand could double over the next two decades in order to meet industrial and consumer demand for electricity produced without burning fossil fuels.

Those officials said 18 potential new customers with high energy needs were looking at setting up operations in Manitoba — and warned the province must be careful to choose businesses that provide the greatest economic benefit as well as the lowest environmental impact.

In a briefing note dated Sept. 13, obtained by CBC News, Manitoba Hydro warns it doesn't have enough excess power to hook up any of these new heavy electricity-using customers to the provincial power grid.

There are actually 57 proposals to use large volumes of electricity, Hydro says in the note, including eight projects already in the detailed study phase and nine where the proponents are working on construction agreements.

"Manitoba Hydro is unable to offer firm commitments to prospective customers that may align with Manitoba's energy roadmap and/or provincial economic development objectives," Hydro warns in the note, explaining it is legally obliged to serve all existing customers who need more electricity.

"As such, Manitoba Hydro cannot reserve electric supply for particular projects."

Hydro says in the note its "near-term surplus electricity supply" is so limited amid a Western Canada drought that "a single energy-intensive connection may consume all remaining electrical capacity."

Adding more electrical generating capacity won't be easy, even with new turbine investments underway, and will not happen in time to meet demands from customers looking to set up shop in the province, Hydro warns.

The Crown corporation goes on to say it's grappling with numerous requests from existing and prospective energy-intensive customers, mainly for producing hydrogen, manufacturing electric vehicle batteries and switching from fossil fuels to electricity, such as to use electricity for heat in buildings.

In a statement, Hydro said it wants to ensure Manitobans know the corporation is not running out of power — just the ability to meet the needs of large new customers, and continues to provide clean energy to neighboring provinces today.

"The size of loads looking to come to Manitoba are significantly larger than we typically see, and until additional supply is available, that limits our ability to connect them," Hydro spokesperson Bruce Owen said in a statement.

Adding wind power or battery storage, for example, would require the construction of more transmission lines, and deals such as SaskPower's purchase depend on that interprovincial infrastructure as well.

Natural gas plants are relatively inexpensive to build but do not align with efforts to reduce carbon emissions. Nuclear power plants require at least a decade of lead time to build, and tend to generate local opposition.

Hydro has also ruled out building another hydroelectric dam on the Nelson River, where the Conawapa project was put on hold in 2014.

European Green Deal Electrification accelerates decarbonization via renewables, electric vehicles, heat pumps, and clean industry, backed by sustainable finance, EIB green lending, just transition funds, and energy taxation reform to phase out fossil fuels.

Key Points

An EU plan to replace fossil fuels with renewable electricity in transport, buildings, and industry, supported by green finance.

✅ Doubles electricity's share to cut CO2 and phase out fossil fuels.

✅ Drives EVs, heat pumps, and electrified industry via renewables.

✅ Funded by EIB lending, EU budget, and just transition support.

The European Union is preparing an ambitious plan to completely decarbonize by 2050. Increasing the share of electricity in Europe’s energy system – electricity that will increasingly come from renewable sources - will be at the center of this strategy, aligning with the broader global energy transition under way, the new head of the European Commission’s energy department said yesterday.

This will mean more electric cars, electric heating and electric industry. The idea is that fossil fuels should no longer be a primary energy source, heating homes, warming food or powering cars. In the medium term they should only be used to generate electricity, a shift mirrored by New Zealand's electricity shift efforts, which then powers these things, resulting in less CO2 emissions.

“First assessments show we need to double the share of electricity in energy consumption by 2050,” Ditte Juul-Jørgensen said at an event in Brussels this week, a goal echoed by recent calls to double investment in power systems from world leaders. “We’ve already seen an increase in the last decade, but we need to go further”.

Juul-Jørgensen, who started in her job as director-general of the commission’s energy department in August, has come to the role at a pivotal time for energy. The 2050 decarbonization proposal from the Commission, the EU’s executive branch, is expected to be approved next month by EU national leaders. A veto from Poland that has blocked adoption until now is likely to be overcome if Poland and other Eastern European countries are offered financial assistance from a “just transition fund”, according to EU sources.

Ursula von der Leyen, the incoming President of the Commission, has promised to unveil a “European Green Deal” in her first 100 days in office designed to get the EU to its 2050 goal. Juul-Jørgensen will be working with the incoming EU Energy Commissioner, Kadri Simson, on designing this complex strategy. The overall aim will be to phase out fossil fuels, and increase the use of electricity from green sources, amid trends like oil majors pivoting to electric across Europe today.

“This will be about how do we best make use of electricity to feed into other sectors,” Juul-Jørgensen said. “We need to think about transforming it into other sources, and how to best transport it.”

“But the biggest challenge from what I see today is that of investment and finance - the changes we have to make are very significant.”

Financing problems

The Commission is going to try to tackle the challenges of financing the energy transition with two tools: dedicated climate funding in the EU budget, and dedicated climate lending from the European Investment Bank.

“The EIB will play an increasing role in future. We hope to see agreement [with the EIB board] on that in the coming months so there’s a clear operator in the EIB to support the green transition. We’re looking at something around €400 billion a year.”

The Commission’s proposed dedicated climate spending in the next seven-year budget must still be approved by the 28 EU national governments. Juul-Jørgensen said there is unanimous agreement on the amount: 25% of the budget. But there is disagreement about how to determine what is green spending.

“A lot of work has been ongoing to ensure that when it comes to counting it reflects the reality of the investments,” she said. “We’re working on the taxonomy on sustainable finance - internally identifying sectors contributing to overall climate objectives.”

Electricity pact

Juul-Jørgensen was speaking at an event organized by the the Electrification Alliance, a pact between nine industry organizations to lobby for electricity to be put at the heart of the European green deal. They signed a declaration at the event calling for a variety of measures to be included in the green deal, reflecting debates over a fully renewable grid by 2030 in other jurisdictions, including a change to the EU’s energy taxation regime which incentivizes a switch from fossil fuel to electricity consumption.

“Electrification is the most important solution to turn the vision of a fossil-free Europe into reality,” said Laurence Tubiana, CEO of the European Climate Foundation, one of the signatories, and co-architect of the Paris Agreement.

“We are determined to deliver, but we must be mindful of the different starting points and secure sufficient financing to ensure a fair transition”, said Magnus Hall, President of electricity industry association Eurelectric, another signatory.

The energy taxation issue has been particularly tricky for the EU, since any change in taxation rules requires the unanimous consent of all 28 EU countries. But experts say that current taxation structures are subsidizing fossil fuels and punishing electricity, as recent UK net zero policy changes illustrate, and unless this is changed the European Green Deal can have little effect.

“Yes this issue will be addressed in the incoming commission once it takes up its function,” Juul-Jørgensen said in response to an audience question. “We all know the challenge - the unanimity requirement in the Council - and so I hope that member states will agree to the direction of work and the need to address energy taxation systems to make sure they’re consistent with the targets we’ve set ourselves.”

But some are concerned that the transformation envisioned by the green deal will have negative impacts on some of the most vulnerable members of society, including those who work in the fossil fuel sector.

This week the Centre on Regulation in Europe sent an open letter to Frans Timmermans, the Commission Vice President in charge of climate, warning that they need to be mindful of distributional effects. These worries have been heightened by the yellow vest protests in France, which were sparked by French President Emmanuel Macron’s attempt to increase fuel taxes for non-electric cars.

“The effectiveness of climate action and sustainability policies will be challenged by increasing social and political pressures,” wrote Máximo Miccinilli, the center’s director for energy. “If not properly addressed, those will enhance further populist movements that undermine trust in governance and in the public institutions.”

Miccinilli suggests that more research be done into identifying, quantifying and addressing distributional effects before new policies are put in place to phase out fossil fuels. He proposes launching a new European Observatory for Distributional Effects of the Energy Transition to deal with this.

EU national leaders are expected to vote on the 2050 decarbonization target, building on member-state plans such as Spain's 100% renewable electricity goal by mid-century, at a summit in Brussels on December 12, and Von der Leyen will likely unveil her European Green Deal in March.
